Process Metallurgy of Wrought CoCrMo Alloy

Source

This paper will describe the processing involved in the manufacture of low and high carbon grades of ASTM Wrought Cobalt-28 Chromium-6 Molybdenum Alloy for Surgical Implants (F 1537) as bar stock for use in a wide variety of biomedical applications. The effect of rolling temperature, annealing temperature, and cold drawing on the mechanical properties and grain size will be explored. Careful control of the thermomechanical working conditions is required to meet high strength requirements because age hardening and cold working of the alloy significantly degrade the ductility while producing the higher strength levels.
